In this paper, an observer design is proposed for linear time delay systems. An easy way to compute least square estimation error of an observer for time delay systems is derived, where the time delay terms exist in the state and output of the system. Based on the least square estimation error an optimization algorithm to compute a Kalman filter for time delay systems is proposed. By employing ...

In this article, we first establish an exponential stability result for a class of linear switched systems and then apply to show the existence distributed observer discrete-time leader system over jointly connected switching networks. Then, further develop adaptive networks, which has advantage in that, it does not require that every follower subsystem know matrix system. As application observ...

<p>The present paper inquire a fuzzy observer design issue for continuous time Takagi-Sugeno aiming at estimating both of fault and state in case unmeasurable premise variables. Thanks to singular value decomposition (SVD) approach, the is synthesized explicit form. The developed method based on augmented structure that assemble actuator fault, sensor as well their sequential derivatives ...

In this paper, new results have been derived for the local observer design for nonlinear control systems with real parametric uncertainty around equilibia. In this paper, it is first shown that equilibrium-state detectability is a necessary condition for the existence of local asymptotic observers for any nonlinear system and using this result, it is shown that for the classical case, when the ...

Statistical modeling of presence-only data has attracted much recent attention in the ecological literature, leading to a proliferation of methods, including the inhomogeneous poisson process (IPP) model [15], maximum entropy (Maxent) modeling of species distributions [12] [9] [10], and logistic regression models. Several recent articles have shown the close relationships between these methods ...

This paper concerns the design of full state observers for state space systems where the state is evolving on a finite dimensional, connected Lie group. Traditional full state observer and filter designs for systems evolving in vector spaces employ the following design principle, going back to the work of Kalman [6] and Luenberger [7] on linear systems. The observer system is designed as a comb...

We use high resolution collisionless N -body simulations to study the secular evolution of disk galaxies and in particular the final properties of disks that suffer a bar and perhaps a bar-buckling instability. Although we find that bars are not destroyed by the buckling instability, when we decompose the radial density profiles of the secularly-evolved disks into inner Sérsic and outer exponen...

The estimation of the full state a nonautonomous semilinear parabolic equation is achieved by Luenberger-type dynamical observer. derived from an output given finite number average measurements on small regions. estimate observer converges exponentially to real state, as time increases. result semiglobal in sense that error dynamics can be made stable for arbitrary initial condition, provided l...
